Perhaps you should try some spelling variations:
yong zhang » kong hang, yan zhang, yuehong zhang
yong phang » kong hang, ying chang
jeong yeon » jeong hyeok, jeang yean, seung yeon
law model » flow model, new model, law codes
ii testi » i testi, ii test, ai test
law past » law part, law east, flow past

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yong zhang) OR (yong phang)) ii testi ((law model) OR (law past)) jeong yeon ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong zhang) OR (yong phang)) ii testi ((law model) or (law past)) jeong yeon ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yong zhang) OR (yong phang)) ii testi ((law model) or (law past)) jeong yeon ;*.
